Sprint Metric ratios
Sprint metrics ratios
These ratios are calculated from sprint metrics.
Excluded Issues in Sprint Metrics Calculation
The following types of issues are excluded from the Sprint Metrics calculation:
Sub-tasks
Sprint metrics are not calculated for sub-tasks.
Outside of Sprint
Issues that were planned and delivered before the start of the sprint are not considered for the Sprint Metrics calculation. These issues are considered "Outside of Sprint" and are excluded since the work was completed before the sprint began, therefore not contributing to the sprint velocity.
Issues Removed in the Mid-Sprint
Issues that were removed from the sprint backlog during the middle of the sprint, before the sprint was completed, are excluded from the Sprint Metrics calculation. Since these issues did not contribute to the planned and delivered work, they are not considered for the calculation.
Commit done ratio
The Commit done ratio is calculated by dividing Commit done points by Commit points. It is the ratio of completed points to committed points, and it indicates how well the team is meeting their commitments in terms of work effort. You can use this ratio to measure team performance in recent sprints.
The Commit done ratio STDEV is the standard deviation of the Commit done ratio. It represents the variability in commit done ratios over multiple sprints.
Commit missed ratio
The Commit missed ratio is the ratio of incomplete points compared to committed points. It highlights the extent to which sprint commitments were not met. The calculation is:
Creep done ratio
The Creep done ratio is calculated by dividing Creep done points by Creep points. It is the ratio of creep points of completed compared to the total creep points committed. It represents how well the team completes additional work that was not in the original sprint plan (scope creep).
Creep done to commit ratio
The Creep done to Commit ratio is calculated by dividing Creep done points by Commit points. It is the ratio of creep points completed compared with the original commitment at the beginning of the sprint.
Creep missed ratio
The Creep missed ratio is the ratio of incomplete creep points compared to total committed creep points. It highlights the extent to which creep commitments were not met. The calculation is:
Creep to commit ratio
Use the Creep to commit ratio ratio to compare unplanned work (known as creep) added to a sprint to the original commitment made at the beginning of the sprint. This ratio is calculated by dividing Creep points by Commit points, and it helps you understand the impact of unplanned work on sprint commitments and overall capacity.
Ideally, this ratio should be below 20%. Higher ratios can indicate that unplanned work is ineffectively managed. Use these benchmarks to analyze your creep to commit ratios:
Low (below 20%): A low ratio indicates that a team is generally successful in managing unplanned work. The majority of the work completed aligns with the initial sprint commitment and unplanned work is minimized.
Moderate (20% to 40%): A moderate ratio suggests that some unplanned work has been introduced, but it is still within acceptable limits. The team is accommodating some level of unplanned work without compromising their main commitments.
High (above 40%): A high ratio indicates that a significant portion of the work completed during the sprint was unplanned. This can signal challenges in managing unplanned work or ineffective sprint planning, potentially leading to difficulties in meeting planned commitments.
The Creep to commit ratio STDEV is the standard deviation of the Creep to commit ratio. It represents the variability in creep to commit ratios over multiple sprints.
Delivered to commit ratio
The Delivered to commit ratio is calculated by dividing Delivered points by Commit points. It is the ratio of points delivered (completed) to the points committed for the sprint.
The Delivered to commit ratio STDEV is the standard deviation of the Delivered to Commit ratio. It represents the variability in delivered points to commit points over multiple sprints.
Done to commit ratio
Use the Done to commit ratio to assess a team's ability to meet their commitments and effectively manage their workload within a sprint. By comparing total completed work to the initial sprint commitment, this ratio provides insight into the alignment of a team's actual capacity with planned commitments for a sprint. It is calculated by dividing the Delivered points by the Commit points.
Use these benchmarks to analyze your Done to commit ratios:
Balanced (around 80%): A ratio of around 80% suggests that a team is challenging themselves while remaining realistic about what can be achieved within a sprint. The team has struck a balance between pushing their capabilities and avoiding overcommitment.
Undercommitted (above 95%): Ratios above 95% indicate that the sprint plan might not be fully leveraging the team's capacity, the team isn't pushing themselves enough, or that their sprint commitments are conservative. This may lead to underutilization of the team's potential.
Overcommitted (below 65%): Ratios below 65% indicate possible overload. Teams might be stretching themselves too thin, and sprint commitments might be unrealistic given the available capacity. Low ratios could lead to reduced quality, burnout, and difficulties in meeting sprint goals.
Scope creep ratio
Scope creep refers to unplanned work or changes that are introduced to a sprint after initial planning and commitment. These unplanned additions can impact a team's capacity and ability to deliver on their commitments. In this context, creep refers to the points associated with unplanned work or changes, and commit refers to the planned points that the team committed to deliver during sprint planning.
The Scope creep ratio provides valuable insights into the impact of unplanned work on the sprint plan and the team's capacity. A high scope creep ratio indicates that a significant portion of the team's effort is being diverted to tasks that were not originally planned for.
It is calculated as the average Creep to commit ratio for all sprints in the selected duration, excluding sprints with 0% creep.
It's important to consider that while zero creep points is a positive outcome that indicates a sprint had no unplanned work, zero commit points is a negative outcome that indicates that no work was committed despite the sprint's existence.
